' 8 Claims. (01. 285-71) an opening either at the upper end, side orlower 10 part of a bag which is provided with circumferential clampingmeans by which the bag, and also the open end of a second bag, may beclamped around the ring providing a hermetically sealed connectionbetween two bags so that the contents is of one may be dumped into theother without escaping into the atmosphere. Bags of this type, andparticularly vacuum cleaner bags, have been provided with closures atthe upper ends which may readily be opened when it is desired to re- 20move the dust from the bag; however, these closures only hold the end ofthe dust collecting bag and when another bag is slipped over the endthereof and dust dumped from one to another, there is an open spacearound the bag permitting the dust to escape therefrom, as there is nodirect connection between the two bags. Other cleaners have beenprovided with vacuum bags of specially treated paper so that the airfilters through the paper, leaving the dust in the bag and the entirebag is destroyed.

removing the dust or other contents from bags by forming a directconnection which positively connects one bag to another with a sealedjoint.

The object of the invention is therefore to provide a coupling forclamping the ends of two bags together with one inside of the other.

Another object is to provide a coupling for connecting the ends of twobags in which the coupling may be inserted in a hem of one bag.

Another object is to provide an attachment by which the open ends of twobags may be positively connected which -.is detachable so that it mayreadily be removed when not in use.

A further object is to provide a coupling for clamping the open ends oftwo bags together in which the clamping parts clamp the ends of bothbags with one over the other.

And a still further object is to provide a coupling for holding the endsof two bags together which provides a sealed connection which is of a 56simple and economical construction.

In both cases it is necessary to break the con- With these ends in viewthe invention embodies an open ring, a goose neck bracket attached tosaid ring and clamping members positioned around the outside of saidring and hinged to said bracket, said clamping members having clamps onthe open endsthereof and said ring adapted to be opened with one endslideable in a socket in the end of the other.

Other features and advantages of the m th-- 5 tion will appear from thefollowing description taken in connection with the drawing, wherein:

Figure 1 is a view showing the attachment with the clamping rings partlyopen and with the dust bag indicated in dotted lines.

Figure 2 is a view showing a dust bag with the attachment incorporatedin the open end thereof and showing the paper bag with the open endplaced over the attachment as indicated in dotted lines..

Figure 3 is a cross section through the attachment with the goose neckshown in full lines.

Figure 4 is a plan view of the attachment with one side partly open.

Figure 5 is a view showing a dust bag with a paper bag held on the lowerend thereof by the attachment and with a cleaning rod therein.

Figure 6 is a view showing an attachment of an alternate design in whichit is formed with a tubular sleeve with clamping bands hinged to theouter surface thereof and with part broken away showing the clampingmeans on the opposite side thereof.

In the drawing the attachment is shown-as it may be made wherein numeralindicates the ring, numeral 2 the upper section of the goose neck,numeral 3 the lower section, numeral 4 one 'of the clamping members andnumeral 5 a complimentary clamping member.

The ring lis preferably made of comparatively small round stock and it.is preferred to make this ring with an 'opening therein in which asocket Sis provided on one end into which the other end! may beinserted, as indicated by the dotted lines 8 shown in Figure 4. Itwillbe understood, however, that an open ring of any type may beprovided and any means may be used for holding the ends together. Theupper section 2 of the goose neck extends upward-from the socket 6,-asshown at point 9 of Figure 3 andthis part bends over so that the rodfrom which the goose neck is formed extends straightdownward with asection It) and then upward forming the section 3. The upper end of thepart 3 is slightly smaller,

- bag placed therein. The parts 4 and 5 extend substantially around thering I and the open ends 1 'are'provided with clamping means as shown inFigures 3 and 4 in which the part 4 is provided with a post I! having-alatch pivotally mounted thereon and'the part 5 is provided with a postit having a link 22 pivotally mounted thereon and it will be noted thata pin 23 shown in dotted lines in the outer end of the link 22 may begripped and held in a socket 24 in the member 20 so that when the latch20 is forced downward against the member 4 it will draw the two memberstogether and clamp the end of the bag or the ends of the bags around themember I. It will be noted that the upper end of the bag may be placedaround a ring i with one side of the bag extending upward into thesection 2 of the goose neck as indicated by the dotted lines 25,

and then another bag may be placed over the upper end oi the former bagwith the side thereof extending downward over the goose neck and intothe socket in the section 3 thereof, as indicated by the dotted lines26. The members 4 and 5 may then be brought together around the ends ofthe bags and clamped together by the members 2| and 22. The upper end ofthe bag 25 may also be provided with a hem, as shown in Figure 1 and theopen end] of the ring I may be inserted in a slit in the hem-and thering may be run around so that it is installed in the hem forming theupper edge of the bag. The end I may then be placed in the socket 6 sothat the device may be installed or mounted in the upper end of the bagand this may be covered with a piece of cloth or a cap of anydescription that may readily be removed when it is desired to place apaper bag or other means for receiving the dust from the dust bag on theattachment.

The device may be installed in the upper end of the bag as shown inFigure 2 in which the bag is indicated by the numeral 21 and it willalso be understood that bags may be provided with these devicesinstalled in both ends or in the upper end and also at a point 28adJacent the lower end so that a paper bag may be placed on the dust bagat the point 28 and the dust shaken into the bag without removing thebag 21 from a vacuum cleaner or the like. These devices may, therefore,be positioned at both ends of the bag or at either end or at any pointtherein.

In the design shown in Figure 5 the bag 21 is shown removed from thesweeper and turned up side down with a paper bag 2! on the lower endthereof and this figure illustrates that the' con-.

necting ring 3| at the lower end of a dust bag may be covered by a cap3| to close this end of the bag and the cap may be provided with a rod3! which may be inserted into the bag for beating the interior thereofin order tofree the dust from the walls. It may also be desirable to usea brush II onthe end of the rod 82 sothat the inner surface of'the bagmay be brushed. It will be understood, however, that anyotheruattachmentsmaybeusedincombinationwith this device for removing dustfrom dust bags or other objects or devices.

In the design shown in Figure 6 the device is formed with the tubularsleeve 34 having c1amp-' ingrings 35 and 38 pivotally mounted on theouter surface thereof with a hinge member 31 and the open ends of thebands 35 and it are provided with clamping means in which a latch 38 ispivotally attached to the end of one section of the ring by a hinge 39and this latch is provided with an opening lfl'whlch fits over a leg orpro- Jection 4| 0n the end of the other section and by forcing the latch38 over the projection 4| it is possible to draw the open ends of thebands SI and 36 together to clamp objects on the suriace to the member34.

It will be understood that other changes may be made in the constructionwithout departing from the spirit of the invention. One of which changesmay be in the use of material of any shape instead of. the round stockshown in Figures 1 to 4; another may be in the use of other means forsupporting the members instead of using the goose neck and another maybe in the use of any other means for hinging the clamping parts at oneside of the ring.

' The construction will be readily understood from the foregoingdescription. In use the device is provided, preferably, as shown inFigure 1 and the ring I may be placed inside of the upper end of a bagor in the hem thereof and another bag placed over the ring and clampedthereto as hereinbefore described. The bag may then be inverted and asit is beaten or shaken, dust therefrom will pass into a secondary bag.This will make it possible for any one using a vacuum cleaner to readilyremove the dust from the dust bag by placing a common paper bag, inwhich groceries or the like have been carried home, with the open endover the ring and clamping it in place. It also makes it possible foranyone to thoroughly clean a dust bag of a vacuum cleaner withoutpermitting dust to escape to the atmosphere so that these bags may becleaned in the home without danger of the dust escaping.

It will also be understood that although this attachment has been shownand described as adapted for use with vacuum cleaners, it may also beused for any other purpose and with bags of any other type ordescription.

Furthermore it will be understood that this device may be used on theopening in the lower end of the dust bag of a vacuum cleaner whichconnects to the discharge of the cleaner, and may be provided as aseparate unit or combined with the collar 30, shown on the lower end ofthe bag in Figure 2, in which case the opening in the .upper end of thebag and also in the side may be omitted.

' This device may also be used to hold a cover, 1 formed of a sheet ofmaterial, over the opening,

in the upper end of the bag, shown in Figure 2, or a cap, cover, orclosure of any description may be used over the device to close theupper end of the bag. The paper bag or container, which is indicated bythe numeral 29, and which may also comprising a ring adapted to beinsertedin the open end of the bag with a holding member attached to oneside, the holding member extending upward therefrom and then extendingdownward beyond the ring, forming a socket, and then extending upwardforming an oppositely positioned socket and clamping means around saidring.
